GE Healthcare StentViz - Manual (Page 2)

Assessing the deployment of stents during
angioplasty procedures is critical for minimizing
the risk of future adverse events.
But accurately assessing stent deployment,
or gauging stent placement in relation to
existing stents, can be highly challenging
with conventional fluoroscopic imaging.
Latest stent designs, low metal content,
bio-degradable materials, steep angulations
and fast stent motion can all obscure stent
visibility.
Innova ® with StentViz provides exceptional
stent visualization, with easy, one-button
activation.
StentViz potentially helps you to:
• Enhance stent visibility and visualization
to assess stent deployment.
• Position stents more precisely with respect
to existing stents.
• Accurately evaluate stent overlap in cases
of in-stent restenosis, long lesions or
bifurcation stenting.
• Increase clinical confidence with immediate
and routine control of stent deployment.
• Save time and money by choosing the right
stenting strategy to avoid additional
procedures and patient re-treatment.
A visualization tool for easily assessing stent positioning
and deployment, StentViz is a perfect fit within your cathlab
workflow. It automatically improves the image quality of
stents from cine X-ray acquisitions.
Unlike other technologies, StentViz detects automatically
both the guidewire and the marker balls to perform an elastic
registration that allows to compensate for non rigid stent
deformation.
In addition, StentViz detects and removes radio-opaque
objects for optimal stent visibility and robust performance.
